In addition to its primary mission of observing space weather, the Deep Space Climate Observatory (DSCOVR) satellite is carrying two instruments that are important to climate science: the NISTAR radiometer and the EPIC camera.

Restoring a healthy balance between sea otters and their sea urchin prey comes with a modest but meaningful bonus: halting the overgrazing of kelp forests and increasing their ability to remove excess carbon dioxide from the atmosphere.

Already a threat to fish, mussels, and other marine creatures, low-oxygen “dead zones” are expected to increase in both size and number as greenhouse gas concentrations and global temperatures continue to rise.

Observations of global temperature going back to 1880 reveal that our planet's temperature is rising. This animation shows maps of yearly temperature compared to the 1981-2010 average from the start of the historical record through 2014--the wamrest year on record. Each year's map is synced with a graph showing the evolution of our planet's temperature as compared to the 20th-century average.

April snow extent was record low across Europe and Asia, and in June, the entire Northern Hemisphere was below average for the tenth year in a row. Spring snow is disappearing even more rapidly than Arctic sea ice in summer.
